I would have preferred seeing more of Celestia after banishing Luna but before Twilight was born. I want to see how she learned to be calm and cheerful around her subjects, but how she dealt with Luna's absence in private. I want to believe Celestia had some tough, lonely moments. There were times in the show were Celestia just didn't emote enough about it, almost making her look like she didn't care that much, which I refuse to believe.
